“Then the priest is to take one of the male lambs and offer it as a
guilt offering, along with the log of oil; he shall wave them before the Lord as a wave offering.” Leviticus 14:12
The
priest shall then wave these before the Lord as a wave
offering; they are holy and belong to the priest,
together with the breast that was waved and the thigh
that was presented… Numbers 6:20
A
wave offering was literally waved in the air to indicate that this offering was
for the Lord. It was a visual emphasis,
a hand signal, to say “this is for you, Lord!”
In
Exodus and Leviticus, we see everything from sacrificial meat (breast, fat),
oil, grain and precious metals (gold, bronze) waved in the air.
